Thanks Colin for your nice words!

I just uploaded the "rulebook" to Google Spreadsheet at http://goo.gl/zKslcu.
It can be used in whatever way, but do read the paper
(http://<http://goo.gl/RnMvG1>
goo.gl/RnMvG1) first to avoid misinterpretation.

Best,

>> version. It seems a daunting and unfeasible task to test these pages
>> exhaustively, hence there has been no well known attempt to gather the
>> complete blacklist.
>>
>> While a small sample of the blacklist is useful, the complete picture

>> examines the entire Wikipedia corpus, hence exposing to the world the
>> complete GFW rulebook for Wikipedia the first time. In total, there are 919
>> rules (excluding URL terms) which are applicable to Wikipedia, affecting
>> 5336 pages in Chinese Wikipedia and 67 English Wikipedia pages.
>>
>> The revealed rulebook also demonstrates that the GFW operation is
>> haphazard and ill-maintained. At the same time, Chinese
>> censorship bureaucracy *intends* to be thorough and extensive.
>>
>> To be precise, the findings in this report are on two Wikipedia
>> snapshots: 2013-09-08 for the Chinese version and 2013-09-04 for the
>> English version.
>>
>> *Conclusion Remarks*
>>
>> In this study, we examined the entire Wikipedia corpus (Chinese version
>> and English version) and revealed the complete and exact GFW rulebook for
>> Wikipedia (with caveats described in Section 6).
>>
>> A sample of notable findings are:
>>
>>    - There are 78 terms for which GFW blocks a non-standard variant but
>>    not the canonical path. These are cases the censors intend to block but the
>>    block does not really happen, suggesting the censors have poor
>>    understanding of Wikipedia's serving system.
>>    - Many obscure non-article pages are blocked, which raises suspicion
>>    that these pages were provided to the censorship bureaucrats by Wikipedia
>>    editors who are very familiar with the content (e.g. those who participated
>>    in the edit wars and/or discussions regarding self-censorship proposals).
>>    - GFW string matching rules have a 64-byte hard limit of size.
>>
>> The biggest learning out of this study, in my opinion, is that GFW

>> is haphazard and ill-maintained. Also, there are many indications that the

>> We hope the revealing can be of interest to internet censorship watchers,
